Abstract

【課題】画像の濃度ムラを低減しつつ、画像の細度を向上させることが可能な電子写真感光体およびこれを備えた画像形成装置を提供する。 【解決手段】本発明に係る電子写真感光体は、基体２０および感光層２１を有する。この電子写真感光体では、露光光Ｌ１の波長に対する反射率を第１反射率とし、除電光の波長に対する反射率を第２反射率としたとき、第１反射率は露光光Ｌ１の光強度率に対して正の相関であり、且つ、第１の場合に第２反射率は露光光Ｌ１の光強度率に対して正の相関であり、第２の場合に第２反射率は露光光Ｌ１の光強度率に対して負の相関である。第１の場合とは、露光光Ｌ１の光強度率の変化量に対する第１反射率の変化量が１より小さい場合である。第２の場合とは、露光光Ｌ１の光強度率の変化量に対する第１反射率の変化量が１より大きい場合である。
